Card linking is a process that connects consumer purchases made with payment cards to rewards, offers, or discounts, providing value for businesses by enhancing customer engagement and loyalty. This system allows businesses to deliver personalized promotions directly linked to a customer’s card, eliminating the need for coupons or codes. By integrating card linking, companies can access valuable insights into consumer spending behavior, which can be used to tailor marketing strategies and improve customer satisfaction. Businesses interested in implementing card linking can use resources like infographics and cheat sheets to determine its suitability and maximize its benefits.
